Choosing Armstrong Clark Oil Based Wood Stains will ensure lasting beauty and protection for all your exterior wood surfaces. Backed by five generations of experience in oil-based coatings and cutting edge technology, Armstrong Clark Wood Stains will not only meet your wood protection needs but far exceed them.

Determine the square footage area of the surface you plan to stain. On decks be sure not only to measure the floor but also railings, spindles, steps and all areas that you are planning to stain. Armstrong-Clark Deck and Siding Stains will cover approximately 150-200 sq. ft. per gallon depending on age and wood porosity.

The Armstrong Clark Staining Instructions

Armstrong Clark Deck and Siding Stains come in many different colors and tones. Keep in mind that the actual color results can vary depending on the type, age, condition, and porosity of the wood. Color samples are available if needed.

Prior to using any of the Armstrong Clark Wood Stains it is important to prepare the wood surface properly so the stain will perform as expected. See the RAD Wood Cleaner or Stain Stripper products for properly cleaning the wood surface prior to staining.

Allow the wood surface to dry 1-2 days after it has been cleaned and prepped. Be sure no rain is expected on the day of staining and for 3-4 hours after application so the stain can cure properly.

To apply Armstrong Clark Deck Stain you can use a roller, brush, stain pad, or airless sprayer. Mix the stain thoroughly prior to use. Unlike other stains, Armstrong Deck Stain can be applied in direct sunlight and on hot days. If the first application of stain penetrates within 30 minutes another coat can be applied for added protection.

If applying by sprayer, use a roller or brush to go over the sprayed areas for a more even appearance. After 24 hours use a dry rag to remove any remaining puddles or glossy areas.

Armstrong Clark Wood Stain is environmentally friendly and does not contain an offensive odor. It is easy to apply and very user-friendly. Enhancing the appearance of your deck and giving it lasting protection is the best investment you can make and Armstrong Clark Oil Based Wood Stains makes it easy.

    Have had a 5 gallon bucket of Semi-Solid Espresso since mid-June, waiting on final weathering of new wood and the forecast to cooperate. Finally looking to get the deck stained and wondering the best way to get the 5 gallons sufficiently stirred and ready to be used. Thoughts?

      Buy a 5-gallon drill paddle that attaches to your drill. Remove lid fully prior to mixing.

    We put on mountain cedar, a semi solid stain a day and a half ago, and it seems to be almost as wet as when we put it on, it is not drying, the temperature is in the low 80s. We took rags and made sure there were no wet spots, how long will it take the deck to dry enough to walk on. It looks wonderful but can’t walk on it.

    I posted around 9/21 but can't find the post.  I had previously asked about installing a tongue and groove front porch under a soffit (Yellow Alaskan Cedar) - whether to stain all sides first or not.   Was advised to install raw, let weather, then sand, clean, brighten, and stain.  We had kiln-dried, acclimatized wood and started the process of raw install this week.  After installing 5 boards, we covered the project due to expected rain, and a few of the "not yet installed" boards got wet and swelled so much we couldn't install them.  We realize we need to let these board dry out before installation, but this got us worried that we have installed tongue and groove boards that fit together without gaps, and if the wood is raw and gets rained/snowed on, especially unevenly, won't the boards swell with nowhere to go, and the floor buckle?  This is taking us back to possibly the need to stain on all sides first, and perhaps allow a very slight (1/16" or 1/32" gap?).  Please advise as soon as possible.

    I stained with AC semisolid on an old deck about 4 years ago. This spring we had deck flooring replaced with new pressure treated pine. I’m ready to stain but don’t want to wait the recommended year for semi-solid on new wood. Can I apply a semi-transparent on the new wood and also over the old semi-solid that is still on the railings? Or should I apply the semi-solid now? It will have been 5 fairly humid months since new wood was installed. 
    • We will reply to your comment shortly
      Armstrong · 08/28/2021
      If you do the semi-transparent now and want to switch to semi-solid later, you will need to strip and brighten for prep. You cannot apply the semi-solid now.

        Amanda Dean · 09/20/2021
        I think we will try the semi-transparent and not plan to switch later. I don't think the old and new woods will match perfectly no matter what. That said, which color of Semi-transparent do you think will most closely match the "Mountain Cedar" color - Cedar or Natural Oak? 
        • We will reply to your comment shortly
          Armstrong · 09/20/2021
          Neither match. Cedar semi would be closed than Natural Oak.

    Just did my 500+ sq Tigerwood deck yesterday for the second time using AC semi transparent mahogany. AC stain just a great product, I'm extremely happy with the results. I have question for this time: I started staining the deck around noon, finished at about 8PM. But being in CA Bay area last night a heavy fog rolled in, in the morning I saw the portion that were late stained has a layer of wet pigment,  my question is: should I just rug them off or using brush to light apply another thin layer? Attached tree picture below: one is dried, 2 are problematic.

    We used a Sherman Williams water based product on our fence a few years ago which has flaked in a few areas crappy product, refuse to use again). We want to refinish with your oil based product (we used this at our cabin and loved it). What is necessary to prepare the fence to switch from water based to oil based?

        The panels are in pretty good shape (no flaking) but you'll see areas on the side of top plate where the existing water-based stain has flaked off. The stain on the top side of the top plate is essentially gone. You'll also see a few new treated posts that were installed over the winter due to storms.  Hopefully this gives you enough.

          The AC cannot go over this coating so it will need to be removed fully first. Unfortunately, it cannot be stripped off fully based on the pictures so you will have to sand to remove it fully.

    With the CA wildfires, air conditions aren't great, and there is even light ash falling periodically.  Realizing that this isn't a paint finish, can I go ahead and knock my project out, or do I need to wait for the ash to stop completely?  I am using semi-trans oil on a deck that I prepped yesterday (when there wasn't any ash).
    • We will reply to your comment shortly
      Armstrong · 08/17/2021
      It should be fine as long as the ash is off the deck and it does not fall on it while it is drying.

    Used brush to apply AC rustic brown semi-trans “maintenance coat” on PT pine deck (original coat was applied last July). Deck was cleaned and nice and dry before applying stain. Three days later, after mid/upper 80s temps with some humidity but no rain, I can see a little residue on a smooth white cloth if I rub the deck hard. It’s not as dark as the stain - it’s very faint. I guess it could even be surface dirt that accumulated over three days since staining. Or maybe even oil residue combined with a little surface dirt. The deck is not glossy and has no puddles or wet spots. The stain seemed to penetrate well - everything looked dry an hour after applying.
    This is the second time I’ve used the same stain, so I’m confident I’m not over-applying based on the results I got the first time I used it (I used less than 3 gallons this time to cover 780 sq ft). What am I seeing? Is it “normal”? Will it go away completely with time - a few more days or a week? Should I wipe it down or just let it be?
    Thanks!

      Armstrong · 07/26/2021
      It probably has not fully cured yet. Give it more time or feel free to wipe down the floors with rags and mineral spirits. If you do this, soak all rags in water when you are done.

        I assume it’s ok to put furniture back on it and walk on it while I wait for full cure?
        If I decide to wipe with rags, will turpentine work or does it have to be mineral spirits?

    First question: I did a deck cleaner followed immediately by deck brightener. It's been a few weeks and it's rained. Is it still ok to apply stain if only a few weeks have passed? Will I need to clean/brighten one more time before staining?

    Second question: I've seen a few videos on Youtube that recommend using an applicator pad, not a roller. Can I use an applicator pad for deck boards with the AC product? Will that give me good/great results? Thanks!
    • We will reply to your comment shortly
      Armstrong · 07/21/2021
      You should lightly clean the deck again since it has been more than 2 weeks. Do not use a roller, use a stain pad or brush for best results.

    Yesterday I posted my good looking deck after 24 hours of application. Now it is about 55 hours, and it seems that the areas that were heavily treated with Armstrong transparent Redwood tone stain, start to burn from inside??? The nuts in the wood became dark black and some can be scraped out, as carbon. Should I spray water on it or call the fire department? Thank you very much.
    • We will reply to your comment shortly

      It is not possible for it to burn but applying water to it will not harm the stain.

        Thank you very much for the good advice. On day 3, the black nuts in the wood, turned into light gray, and I assume as time passes, it will blend in more with the wood color. I did not spray water on it, as you assured me that it will not start to burn. Thanks again!

    I used many times the redwood tone transparent stain with great success. This year I hired a company to do it for me. They used the RAD cleaner, brightener and transparent redwood tone stain. They used brushes for application, in a very thorough manner. After 24 hours the wood is still greasy to touch. Should they apply a second coat? I am asking this because when I used to do it, I always needed a second coat. Would it help or harm if the second coat was added. Until now they used 5 gallons of stain on a 1000 square feet area. I still have 2 gallons left. The railings are dry to touch. Thank you in advance for your advice.

    I plan to brush on semi transparent rustic brown, how to do so to avoid over applying. I see many comments that say stain is still picking up after application even after weeks. What do you suggest to ensure applying the ‘just right’ amount?

      Armstrong · 07/14/2021
      AC is very easy to apply and doe not get overlap lines. Just use an exterior stain pad for the floors and a brush as needed. Apply only as much as the wood allows the stain to fully soak in. More is not better when it comes to penetrating deck stains.

    I have a 20+ year old IPE deck thats not been treated, only pressure washed every 3-4 years.  The railings and spindles are cracked and split.  Our deck guy recommended Armstrong Clark Mahogany positive dry. Is there a product called positive dry?  He also recommended sanding the rails and posts, should I do that before or after the cleaning, prepping, and pressure washing?

    I prepped my deck by using deck cleaner followed by brightener.  It is going to be close to 100 degrees F tomorrow.  Do I still need to wait two days before I apply the stain?  If I need to wait the full two days, were are expecting a lot of rain at that point.  And right after the rain, I will be unavailable for about two weeks.  Can I apply the stain three weeks after the prep, or do I need to redo some of the prep?
    Thanks

      Yes, you should wait 48 hours after prep. You should redo prep if longer than two weeks. Light wash and brighten.

        Curious, why redo prep after two weeks, why wouldn’t 3 or 4 weeks be okay? My deck is 500 sq feet and to light wash and brighten properly ( in 5 sections, keeping it wet for a 20 minute wait, then thorough rinse) it would take 6 hours to complete. Is this the same process you are referring to when  suggesting. ‘light wash and brighten’?
        Fingers crossed that my stain order arrives next week :)

          The wood will get dirty again the exposed wood cells will oxidize. You can redo the wash and brighten this deck in an hour if needed. Do it all at once, not in 5 sections.

        Oh, I wasn’t considering Amber because it wasn’t on the semi transparent list. But I can see the colour is similar. The deck is 30 years plus in some areas. In the choice of Amber were you also considering the wear on the deck and how a semi transparent would look verses a semi solid?Appreciate your input. Already spent tons of hours preparing it want to get it right. 
        Also, I live in Canada and would have it shipped, anyway to estimate shipping cost through purolator?
